You can trivially use pg_buffercache for view this, and its code in
contrib/pg_buffercache will show you how to navigate the buffer cache data
too. There's example of how to use it in the documentation for that
module and I've got some additional ones on my web page at
http://www.westnet.com/~gsmith/content/postgresql in the slides and
examples for "Inside the PostgreSQL Buffer Cache".
